Finding Serial Port Information for Your Platform

The ways to find serial port information for Windows and UNIX platforms are described below.

Windows Platform

You can easily access serial port information through the Windows Control Panel. You can invoke the Control Panel with the Start button (Start -> Settings -> Control Panel).

For Windows NT, you access the serial ports by selecting the Ports icon within the Control Panel. The resulting Ports dialog box is shown below.

You can access serial port information for the Windows 2000 operating system with the System Properties dialog box, which is available through the Control Panel.

UNIX Platform

To find serial port information for UNIX platforms, you need to know the serial port names. These names might vary between different operating systems.

On Linux, serial port devices are typically named ttyS0, ttyS1, and so on. You can use the setserial command to display or configure serial port information. For example, to display which ports are available

To display detailed information about ttyS0

For all supported UNIX platforms, you can use the stty command to display or configure serial port information. For example, to display serial port properties for ttyS0

To configure the baud rate to 4800 bits per second
